Leather Goddesses of Phobos on the Commodore 64 is Infocom’s cheeky sci-fi comedy text adventure where you play a regular person caught up in an alien invasion led by glam, dominatrix-styled extraterrestrials. You bounce between Earth and the strange world of Phobos, solving classic Infocom puzzles with a steady stream of innuendo, absurd situations, and playful fourth-wall winks. It’s famous not just for the risqué humor but for offering different “naughtiness” levels, letting you choose how spicy (or mild) you want the adventure to be.
